Answer:

3600

Step-by-step explanation:

\text{Compounded Continuously:}

Compounded Continuously:

A=Pe^{rt}

A=Pe  

rt

 

P=1800\hspace{35px}r=0.047\hspace{35px}t=15

P=1800r=0.047t=15

Given values

A=1800e^{0.047(15)}

A=1800e  

0.047(15)

 

Plug in

A=1800e^{0.705}

A=1800e  

0.705

 

Multiply

A=3642.92403286

A=3642.92403286

Use calculator (with e button)

A\approx 3600

A≈3600

in a choir the ratio of men to woman is 4:7. 25% of the men prefer classical songs, and 80% of the women prefer classical songs.
Paraphin [41]

Answer:

60%

Step-by-step explanation:

percentage of men in the choir = (4/11) x 100 = 36.4%

percentage of women in the choir = (7/11) x 100 = 63.6%

Percentage of men in the choir that prefer classical songs =  36.4 x0.25 = 9.1%

Percentage of women in the choir that prefer classical songs = 0.8 x 63.6% = 50.9%

percentage of the choir prefer classical songs = 50.9% + 9.1% = 60%

Find f(-2) for the function:<br><br> f(x)= 3x^2-1, x&lt;1<br> x+2, x&gt; 1
azamat
F(x) = 3x² - 1
f(-2) = 3(-2)² - 1
f(-2) = 3(4) - 1
f(-2) = 12 - 1
f(-2) = 11

f(x) = x < 1
f(-2) = -2 < 1

f(x) = x + 2
f(-2) = -2 + 2
f(-2) = 0

f(x) = x > 1
f(-2) = -2 > 1
f(-2) = -2 < 1
